COMPANY, on NEW YORK, N. Y., A CORPORATION or NEW JERSEY CHIMNEY PIPE STRUCTURE Application filed. August 11, 1927. Serial No. 212,158.

My invention relates to new and useful improvements in chimney pipe structure, and more particularly to a device for coupling adjacent chimney pipe sections.

An object of my invention is to provide asimple and eflicient coupling device.

Another object is to provide a device Which will retain joint sealing material.

Still another object is to provide a device which adjacent sections are alined.

- The invention consists in the improved construction and combination of parts to be more fully described hereinafter, and the novelty of which will be particularly pointed of adjacent pipe sections. This member 1 has a continuous closed surrounding wall or sleeve 2, the internal face of which tapers downward or converges from its top 3 toward its bottom. 4. The sleeve 2 has, in elevation the form of 'an inverted isosceles trapezoid having its base of lesser dimension at the bottom 4.

Within the wall or sleeve 2 are members, preferably in the form of lugs which are fixed to the wall and project inwardly therefrom in a plane parallel to and intermediate the bases of the trapezoid or the top 3 and bottom 4 of the sleeve 2. These members or lugs 5 are'spaced apart to provide passages 6 for a purpose to be described. Preferably carried by the lugs 5 and in their common plane is a continuous closed flange 7 spaced from the inner face of the wall 2.

Between the base of larger dimension or top 3 and the lugs 5, I provide alining or positioning means 8, preferably in the form of vertical spaced lugs. The inner ends of the positioning means or lugs 8 terminate in a line through the intersection of the plane of the base of lesser dimension or bottom 4 and the inner face 9 of the wall or sleeve 2, and which extends transversely or'at right angles tothe plane of lugs 5. It will therefore be seen that the linear"distances in parallel planes from the centerline of sleeve 2 to the lugs 8 are equal to the linear distances from the centerline to corresponding points on the inner face of sleeve 2 in its plane of minimum area,namely, at the bottom 4. The lugs 8 preferably extend from the inner sleeve face 9 to the upper surface 10 of lugs 5, and have a downward and inward inclined upper edge 11.

The coupling above described, inclusive of the sleeve 2, the lugs 5, flange 7, and positioning or centering lugs 8, is preferably cast in a single integral casting of a suitable metal.

The use of the member'l is as follows: A pipe section, such as 12, is set and secured in position. My improved coupling member is then placed over the upper end of the section 12, it of course being understood that the pipe sections and the coupling member are of similar plan outline, and that the coupling member be of roper size to fit the sections to which it is to e applied. When the member 1 isproperly positioned upon the section 12, the flange? and the inner ends of lugs 5 will rest upon the upper end .13 of the section, with the inner edge 14 of. flange 7 substantially flush with the inside of the pipe section, and the face 9 of sleeve 2 at its bottom 4 will engage the outside surface 15 of the lower pipe section 12. Another section16, to be the next above, is now placed with its lower end within the sleeve 2. The bottom end 17 of this section 16 will seat upon the lugs 5 and flange? and within the lugs 8. By reason of the'upper inclined edges 11 oflugs 8, the section 16 will be in proper alinement with section 12 when the section 16 stands vertically. A suitable binder 18, such as cement or grout, is then poured into the'tapered annular space between the pipe sections 12, 16 and the sleeve 2 to seal the joint between the sections. The binder 18 will flow through passages 6 to surround the lower section 12 and will be prevented it'rom flowing into the pipe by reason of the flange 7 The coupling member 1 is preferably made of cast-iron, but any other suitable material may be employed. Although I have shown member 1 as substantially rectangular in plan view, it is of course understood that the plan outline may be, varied as desired to suit the member l to the type of pipe with which it is tobeused.

What I claim and desire to secure by Letters Patent of the United States-is 1. A joint sealing material retaining member for pipe joints, comprising a hollow wall member of isosceles trapezoidal form in side elevation having its base of lesser area con 7 oint.

forming to the external contour of a pipe section to closely surround the section, and wall member supporting means extending inwardly intermediate the bases of said member to be clamped between the meeting edges of adjacent pipe sections to hold said member rigidly in material receiving posi: tion and spaced from the meeting ends of the sections, said means being apertured for v the passage of sealing material therethrough.

2. A device of the character described, comprising an internally downward converging sleeve adapted to surround the meeting ends of adjacent pipe sections to form a tapered sealing material receiving space between the sleeve and the pipe sections, spaced'lugs on said sleeve projecting inwardly intermediate the ends thereof, and

a continuous flange in the plane of'said lugs and carried thereby, said flange being of a thickness substantially equal to the thickness of said lugs, said flange and lugs being adapted to lie and be clamped between the meeting ends of adjacent pipe sections'thereby to support said sleeve at and around the I 3., A chimney pipe joint member, comprising a retaining Wall member adapted to surround the joint formed by the meeting ends of adjacent pipe sections, said wall member co-operatingwiththe external surface of the meeting ends of the adjacent sections to define a sealing material receiving space, and supporting means having provision for passage of sealing material therepast into. the space between said member and the lower pipe section and projecting inwardly from i said wall to hold the retaining ,wall member at and around the joint, said means adapted to lie between the section meeting ends and be clamped thereby to hold the wall member in operative position.

4. A joint sealing material retaining member for a chimney pipe joint, comprising a wall member having inwardly projecting means to be clamped between the meeting ends of adjacent chimney pipe sections to hold the wall member at and around the said wall member intermediate the top and bottom thereof to overlie and rest upon the end of a pipe section to support said wall ried by said wall member to alinethe end of a secondpipe section with the first section, said positioning means havinganinclined guiding surface for engagement by the external periphery of the end of the member thereon, and positioning means carv second pipe section whereby the second pipe l I section is guided into alinement as it is seated on sald spaced members.

6. A device ofthe character described,

comprising an internally downward tapered surrounding wall member adapted to surround the joint between adjacent pipe sections of uniform cross-section and to: engage at. its lower end the external face of a lower pipe section to thereby center said member on the section and define therewith a sealing material receiving space, means projecting inwardly from said wall member intermediate its ends to support the wall member at the joint and on the lower pipe section, and means projecting inwardly fromv-said wall member above said supporting means to guide an upper pipe section into alinement with the next adjacent lower pipe section.

7. A device of the character described, comprising an internallydownward tapered sleeve having the endof smaller dimension adapted to surround and engage the upper end of a'lower pipe section to center said sleeve with respect thereto and to define therewith a sealing material receiving space, lugs projecting inwardly from said sleeve for overlying engagement with the upper end of the pipe section, and means projecting inwardly from said sleeve above said lugs to guide an upper pipe section to be seated on said lugs into alinement with the lower section.

10. A device of the character described, comprising an internally downward tapered sleeve having spaced lugs projecting inwardly from the inner face of said sleeve, a flange carried by said lugs, and positioning means projecting inwardly from said sleeve and terminating substantially equidistant from the center line of said sleeve to corresponding points in the plane of least area of said sleeve. I
